FreePBX HA-Hardware Requirements
- Lorne Gaetz (Unlicensed)
Prerequisites
FreePBX HA requires two reasonably identical machines. It's preferable if you have EXACTLY identical machines, to ease configuration issues. While there is currently no official Hardware Compatibility List, server class hardware is strongly recommended.
| Minimum | Preferred |
|---|---|---|
CPU | i5 class | Quad Core Xeon or greater |
RAM | 2 GB | 4 GB + |
HDD | 100 GB | 250 GB + |
NIC | 1 Network Interface | 2 Separate Network Interfaces. IPMI on dedicated NIC. Most server-class hardware comes with IPMI (such as Dell's DRAC, HP's ILO, etc.) to enable the cluster to manage the power state of each node. |
Virtualization
Virtualizing FreePBX-HA is supported when used with Asterisk 11, but at time of writing (B1) no management is available. Currently supported:
VMware ESXi (5.1 or greater)
VMware Workstation (10 or greater)
OpenStack
Solus with KVM
While other Virtualization systems will, most probably, work with FreePBX HA, we can't guarantee that we'll be able to offer any assistance with problems related to any other systems.
